The husband of missing Gold Coast mother Novy Chardon has been fingerprinted and swabbed for DNA after being interviewed by police for more than three hours.

John Chardon returned to Australia from an Indonesian business trip with the couple's two children on Saturday and visited Coomera Police Station about 11am on Monday.

Police described it as a "routine" event.

Detective Superintendent David Hutchinson stressed Mr Chardon had not been arrested and was not even a suspect.

"It [the forensic order] is normal routine in this kind of investigation," he said.

Mr Chardon flew to Indonesia with the couple's two children on a pre-arranged business trip two days after his wife disappeared from their Upper Coomera home on February 6.

On Saturday, the day he reportedly returned to Australia, he said he had nothing to do with his wife’s disappearance.

‘‘All I will say is that I did not f---ing do anything to her and we don’t know where the f--- she is,’’ he told News Ltd.

‘‘There's a lot more complication to it.’’

He would not elaborate on what that meant.

Last week police and State Emergency Service volunteers searched a quiet road behind the theme park Movie World, in their hunt for clues about the missing woman.

Police believe Mrs Chardon’s Volvo four-wheel-drive wagon may have been driven along the road some time between her disappearance and the evening of February 11 when it was found.

Mr Chardon's Loganholme lubricant business, Candan Industries, was raided by police officers who took computers and other items last week.

SES volunteers have scoured bushland in the hunt for the mother, and police divers were called in to search the Nerang River for any clues.

In the course of the investigation detectives released CCTV stills of Mrs Chardon and a female friend at a Coomera service station and soon after at the Upper Coomera McDonald’s drive-through on the night she disappeared.

Mrs Chardon’s Volvo four-wheel-drive was discovered at Nerang railway station after her disappearance but the magnetic signs advertising her beauty business had been removed.

Mr Chardon’s car, which was parked at Brisbane Airport, and the couple’s Bridie Drive home have also been searched as routine parts of the investigation, according to police.
